我正在爲WCF服務開發Android客戶端。有一個Windows應用程序,與服務一起工作,沒有任何問題。但是,當我嘗試使用Android上的服務時,使用kSoap2 - 我得到500內部服務器錯誤。顯然,我做錯了什麼,但無法弄清楚什麼。使用ksoap2在Android上使用WCF服務 - 內部服務器錯誤
這裏是我的Java代碼:
// SOAP consts
private static final String NAMESPACE = "http://tempuri.org/";
private static final String SERVICE_NAME = "/SignService";
private static final String SOAP_ACTION = "http://tempuri.org/ISignService/";
...
String url;
String method_name = "GetExistedSignData";
url = mServerAddress + SERVICE_NAME;
/* the connect logic goes here */
try {
SoapObject request = new SoapObject(NAMESPACE, method_name);
request.addProperty("displayId", "HWI_00:1E:8C:87:7F:8D");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
envelope.dotNet = true;
//envelope.implicitTypes = true;
envelope.setAddAdornments(false);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(url);
androidHttpTransport.call(method_name, envelope);
sb.append(envelope.toString() + "\n");
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
//to get the data
String resultData = result.toString();
sb.append(resultData + "\n");
} catch (IOException e) {
sb.append("IO Problem:\n" + e.getMessage() + "\n");
} catch (XmlPullParserException e) {
sb.append("Parser Problem:\n" + e.getMessage() + "\n");
}
catch (Exception e) {
sb.append("Error:\n" + e.getMessage() + "\n");
}
下面是Windows客戶端的HTTP轉儲成功地調用一個方法:
POST /SignService HTTP/1.1
Content-Type: application/soap+xml; charset=utf-8

這裏是我的不成功調用相同方法的HTTP轉儲:
POST /SignService HTTP/1.1
User-Agent: ksoap2-android/2.6.0+
Content-Type: application/soap+xml;charset=utf-8
Connection: close

<displayId>HWI_00:1E:8C:87:7F:8D</displayId>
</GetExistedSignData>
</v:Body>
</v:Envelope>
作爲回報,我得到:
HTTP/1.0 500 Internal Server Error

Pragma: no-cache
Cache-Control: no-cache

錯誤描述的最有用的部分說:
Error Code 64: Host not available
Background: The connection to the Web server was lost.
我不是很熟悉,WCF和.NET所以我出什麼可能是錯誤的選擇。我沒有開發我需要在Android中使用的WCF服務。
其他選擇是什麼? – ozmank
